Specification of Letters Patent.

To all whom it may concern.'

Be it known that I, CARL RAsMUssEN, engineer, a subject'of theKing of Norway, residing at Leipzig, Germany, have invented certain new and useful Improvements in Calculating-Machines, of which the following` vis a specification.

My invention relates to improvements in I calculating machines, and more particularly in calculating machines of that class, in which the setting mechanism consists of setting disks provided with radially shiftable teeth corresponding to the values to be transmitted to the registering mechanism, and cam disks for shitting the desired number ot the teeth ot' the setting disks into operative position, which cam disks are provided with handpieces projecting through slits made in the cover of the casing of the 1nachine. A machine 4o" this lconstruction is shown for example in United States Patent No. 823.375 granted' to Franz Trinks June 1,2, 1906. These hand pieces which are directly connected to or made integral with the cam disks are very short in machines in use, so that the operation of the same is inconvenient. For this purpose efforts have been made to provide the said hand pieces with extensions, as is shown for example in United States Patent No. 979,358, granted to Franz Trinks December 20, 1910, which construction however, is more or less complicated. In all these constructions the set` ting members do not take part in the movement of the setting and cam disks, which is necessary, because otherwise the setting members would be brought by the rotation ct' the cam disks into engagement with the shaft of the intermediate gear wheels which have the saine number of teeth as the gear wheels of the numeral wheels. -This however is not necessary, and all that is neces- ,fzarv is that lthe intermediate gear Wheels shall he in correctengagement with the gear wheels. of the numeral disks.

My invention is based on this fact, and it consists in providing in my improved machi ne intermediate gearwheels the diameter ot' which is so, that the distance between the shafts of the setting mechanism and of the intermediate gear wheels is greater than that between the shaft/of the setting mechanism and the free ends of the aforenwntioned hand pieces, so that the latter can be made sufficiently long without contacting 'the same.

, hersprovided with radially with the shaft wheels. 1I

F 0r-the purpose of explaining the invention an example embodying the same has beentshown in the accompanying drawings in which the same letters of reference have been used in all the views to indicate corresponding parts.

In said drawings Figure l, is a front view of the machine with the cover of the casing partly broken away and some of the numeral disks, intermediate gear Wheels and setting disks omitted, and Fig. 2, is a crosssection taken 0n the line 2 2 f Fi 1.

The setting mechanism consists oeetting disks b and coperating cam disks 'd which are mounted in the usual way on a shaft a adapted to be rotated from a cranko through the intermediaryof gear Wheels al and a2. The cam disks are providedin' the usual way with hand pieces d for operating l In front of the setting' mecha.- msm a carriage g is slidably mountediwhich carries the registering mechanism consisting of numeral disks m and gearwheels le connected therewith. In the carriage a shaft. h is mounted which carries. intermediate gear wheels t' which are in mesh with the gear wheelstlc of the registering mechanism, and are adapted to be operated by the teeth a of the setting mechanism.

As appears from the eter of the intermedi ate ear wheels i is considerahly larger than th t ofthe wheels k. Thereby I am enabled to provide the setting disks with hand pieces d', which' are considerably longer than those which are provided in machines now in use. Incases in which above the setting mechanism b, d, digit drums n are providedv whicharejlikee wise operated through intermediate gea-r wheels z, the diameterof the said inter-` mediate gear wheels is likewise so large, that the hand pieces d can pass thershafty of the wheels ai. I I

I claim herein as my invention: i

of the intermediate gear drawings the diam i, i

1. In a calculating machine, the co'rlnbirmli` tion with the setting mechanism comprising setting disks and -coperating setting mem'- p'rojecting hand nieces, of a registering mechanism comprimi..A

ing numeral disks and gear wheels, and in termediate gear wheels interposed between the setting disks and the first-named gear Wheels, the distance between the axis of said seiiiig diSks and setting n'reiiibers and the axis of said intern'iediate gear W reels being grenier than that between the irstmu, d zrxis mid the free ends of smid hand pieces.

2. ii a ealeulnng mmiineT the combination with the setting 'meeharisan'i comirising set-ting disks and setting members therefor provided with radin-)1y 'projecting hand pieces, of numeral disks, gear Wheels C011- 10 heated with the nurfierai dissks and inerme dime gear wheels interposed between the first named gear wheels and the setting disks, the dismice between the axisvef smid setting disks :md setting: members and the e" smid iiieiriri" rite geur Wheeiss being greater their that bei-Ween the ist'1z:i1ned axis and the free ends ef said prejeC'ti-ims.
